[0005] Accordingly, a treading exerciser comprises a base frame, a first treadle plate, a second treadle plate, a hydraulic pressure control device, a first power control device, and a second power control device. The base frame has a front support frame, a rear support frame, and a connection panel connected to the front support frame and the rear support frame. A first sleeve is disposed on an end of the first treadle plate. A first pivot shaft is inserted through the first sleeve. A second sleeve is disposed on an end of the second treadle plate. A second pivot shaft is inserted through the second sleeve. The hydraulic pressure control device is disposed on the connection panel. The first power control device is connected to the hydraulic pressure control device and the first treadle plate. The second power control device is connected to the hydraulic pressure control device and the second treadle plate. An adjustment shaft is inserted through the hydraulic pressure control device. A control rod is disposed on the adjustment shaft.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Referring to FIGS. 1 to 11, a treading exerciser comprises a base frame 1, a first treadle plate 2, a second treadle plate 3, a hydraulic pressure control device 6, a first power control device 4, and a second power control device 5.

[0022] The base frame 1 has a front support frame 11, a rear support frame 12, and a connection panel 13 connected to the front support frame 11 and the rear support frame 12.

[0023] A first sleeve 21 is disposed on an end of the first treadle plate 2.

[0024] A first pivot shaft 15 is inserted through the first sleeve 21.

[0025] A second sleeve 31 is disposed on an end of the second treadle plate 3.

[0026] A second pivot shaft 18 is inserted through the second sleeve 31.

[0027] The hydraulic pressure control device 6 is disposed on the connection panel 13.

[0028] The first power control device 4 is connected to the hydraulic pressure control device 6 and the first treadle plate 2.

[0029] The second power control device 5 is connected to the hydraulic pressure control device 6 and the second treadle plate 3.

[0030] A post 14 is disposed on the front support frame 11. A counter 16 and a button 17 are disposed on the post 14.

[0031] An adjustment shaft 66 is inserted through the hydraulic pressure control device 6.

[0032] A control rod 661 is disposed on the adjustment shaft 66.

[0033] The hydraulic pressure control device 6 has an outer cylinder 64, an inner cylinder 67 engaging with the outer cylinder 64, a piston 664 disposed in the outer cylinder 64, a rotating cover 61 surrounding the inner cylinder 67, an inner interior 68 defined between the outer cylinder 64 and the piston 664, and the adjustment shaft 66 passing through the rotating cover 61 and the piston 664.

[0034] A first oil channel 41 is formed between the first power control device 4 and the hydraulic pressure control device 6 to receive a hydraulic pressure oil 7.

[0035] A second oil channel 51 is formed between the second power control device 5 and the hydraulic pressure control device 6 to receive the hydraulic pressure oil 7.

[0036] The first oil channel 41 communicates with the second oil channel 51.

[0037] The rotating cover 61 has an embossed annular portion 63 and an inner threaded portion 62.

[0038] The outer cylinder 64 has an outer threaded portion 65 engaging with the inner threaded portion 62 of the rotating cover 61.

[0039] When the rotating cover 61 rotates upward, the piston 664 will move upward and a lot of hydraulic pressure oil 7 will enter the inner interior 68 of the outer cylinder 64. Then an angle of elevation of the first treadle plate 2 and an angle of elevation of the second treadle plate 3 will be small.

[0040] The adjustment shaft 66 has a threaded end 662 inserted in a spacing 663 between the first oil channel 41 and the second oil channel 51.

[0041] The threaded end 662 of the adjustment shaft 66 has a plurality of spacings 663.

[0042] The hydraulic pressure oil 7 enters the second oil channel 51, the inner interior 68 of the outer cylinder 64, and the first oil channel 41.

[0043] When the adjustment shaft 66 moves upward, a room of the spacing 663 becomes large so that a damping force becomes small.

[0044] The invention is not limited to the above embodiment but various modification thereof may be made. Further, various changes in form and detail may be made without departing from the scope of the invention.
